Uloboridae Thorell, 1869 - Cribellate Orb Weavers

Kingdom: Animalia
Class: Arachnida
Order: Araneae
Family: Uloboridae

Uloboridae is a family of nonvenomous spiders, known as cribellate orb weavers or hackled orb weavers. Their lack of venom glands is a secondarily evolved trait. Instead, they wrap their prey thoroughly in silk, cover it in regurgitated digestive enzymes, and then ingest the liquified body. All members of this family produce a feathery, fuzzy silk called cribellate (or hackled) silk. These spiders do not use an adhesive on their orb webs, but rather the very fine fibers on each strand of silk tend to ensnare prey. Uloboridae webs often have a stabilimentum or zig-zag pattern through the center. Wikipedia
